LEROY J. SULLIVAN BY ATTOPNEY5 United States Patent 3,178,845 RIFLELeroy J. Sullivan, 14542 Cork St., Garden Grove, Calif. Filed Apr. 29,I963, der. No. 276,383 15 Claims. (Ci. 42-17) This invention pertains toan arrangement for automatically supplying a cartridge for each firingcycle of a gun.

The arrangement of this invention is particularly useful in providing anautomatic feed arrangement for rifles. There have been numerous previousproposals for cartridge feeding devices of this general character, butgenerally these have been unreliable in performance and of less capacitythan the present invention. Normally, too, the prior cartridge feedingarrangements have been complicated and relatively costly to construct.

The present invention includes an elongated magazine holding a quantityof cartridges standing in substantially an upright position when the gunis in its normal horizontal alignment. A spring in the magazine pushesthe cartridges toward a rotatable lifter which is spring loaded to movethe cartridges individually into the gun. The cartridges are pivotedonto the lifting device rather than being translated for this movement.This reduces the distance the entire number of cartridges must be movedin feeding to the lifter, reducing inertia effects and speeding up thefeed cycle. As the lifter rotates, the rim of the cartridge is guided,while inwardly the cartridge pivots about a fulcrum so that it is causedto rotate 90. The fulcrum is yieldable to permit the bullet ultimatelyto pass it and enter the gun. Forward movement of the gun bolt drivesthe lifter down to accept the next cartridge. The return stroke of thebolt releases the lifter so that the feeding cycle is repeated.

Accordingly, it is an object of this invention to provide an automaticcartridge feeding device.

Another object of this invention is to provide a cartridge feeder ofreliable performance yet which can be manufactured at a low cost.

A further object of this invention is to provide a cartridge feedingdevice compact in size, yet of large capacity.

An additional object of this invention is to provide a cartridge feederhaving a magazine that is easily loaded and unloaded.

Yet another object of this invention is to provide a cartridge feedingdevice capable of extremely rapid operation.

These and other objects will become apparent from the following detaileddescription taken in connection with the accompanying drawing in which:

With reference to the drawing, as seen in FIGURES l, 2 and 3, thecartridge feeding device of this invention is illustrated as used with agun 15 which in this embodiment is a .22 caliber long rifle. The stock,which can be made to cover the cartridge feeding device, has beenremoved for clarity.

The invention is particularly adapted for use with a gun that fires fromthe open bolt position. Hence, the bolt 16 of gun 15 can be pulledrearwardly by means of laterally projecting lever 17, where detent 18 ofthe trigget 19 holds it in the cocked position. Upon release of thetrigger the bolt 16 will be driven forwardly by a spring 28 toward thegun barrel 2i, and will chamber and fire the round 22. The blowback ofthe gases from the fired cartridge forces the bolt to the rear,returning it to its cocked position. Upon this movement an extractormounted on the bolt removes the cartridge from the chamber and causes itto be flipped out of the opening 23. These features are of generallyconventional construction.

The cartridge feeding arrangement of this invention includes anelongated magazine 24 from one end of which projects a tube 25 (seeFIGURE 4). A fitting 26 secures the tube beneath the muzzle of the gun.The magazine includes a longitudinally extending opening 27 which isadapted to receive the quantity of the cartridges 22. In a typicalexample, the opening 2'7 may be dimensioned to accommodate fifty rounds.

A plunger 28 is slidable in the opening 27 and engages the innermost oneof the stack of cartridges 22 in the magazine. The plunger 28 is biasedto the left as illustrated by means of a compression spring 29 receivedin the tube 25. A rod 30 projects from the plunger into the spring andassists in guiding the spring as it enters the magazine. It can be seen,therefore, that with the cartridges 22 in the magazine the spring loadedplunger 28 urges the group of cartridges to the left as the device isillustrated.

The cartridges, of course, are of conventional design which includes anelongated substantially cylindrical central portion 32 with a roundedbullet nose 33 at one end and a rim 34 at the other. Because the latterportion of the cartridge is of the greatest diameter the magazine iscontoured so that the cartridges may assume the slightly tiltedpositions illustrated in FIGURE 5. This allows the cylindrical portions32 of the cartridges to be brought into engagement with each other, andpermits the rectilinear alignment of a considerable number of thecartridges While maintaining them in a firm contacting relationship. Tothis end, therefore, the central side wall portions and 36 of theopening 27 are convergent toward the top while the upper portion 37 ofthe opening is enlarged. Base walls 38 and 39 are normal to the walls 35and 36 respectively, and the side edges 40 and 41 of the magazine extendoutwardly from the sides 35 and 36. This gives clearance for thecartridges to tilt, with the rims being received at the base and held bythe shoulders between the walls 35 and 40 and 36 and 41. The pressure ofspring 29 will cause the cartridges to assurne the relationships shownwith alternate cartridges inclining in opposite directions. Thus, in themagazine 24 the cartridges are held beneath the gun barrel substantiallybut not quite in vertical alignment when the gun is in its normalhorizontal position.

At the end 43 of the magazine 24 the outermost rounds 22 are fed betweenvertical guide walls 44 and 45 as shown in FIGURES 2 and 6. The upperedges 46 and 47 of these walls are arcuate, curving downwardly to thebottom edges where the cartridges enter. This allows the cartridges tobe introduced smoothly into the space between the walls 44 and 45despite their prior slightly angular relationship. The walls 44 and 45cause the cartridges to be in precise perpendicular alignment withrespect to the gun barrel at the end 43 of the magazine. The slots forthe rim 34 prevent vertical movement of the round 22 at the end 43 ofthe magazine.

Immediately adjacent the end 43 of the magazine, and in alignment withthe cartridges in the magazine as held between walls 44 and 45, is arotatable lifter 49. The lifter 49, which acts as a drive member to movethe cartridges from the magazine to the gun receiver, is in the form ofa flat plate mounted on a cross shaft 50. The latter element is held bya pair of sheet metal members 51 and 52 that project beyond the end 43of the magazine. Torsion spring 53 is carried on the pin and engages theedge 54 of lifter 4?. This biases the lifter to its upper position seenin FIGURES 1, 2 and 3. A stop tab 55 projects from the side of thelifter adjacent the edge 54 and engages the member 52 to limit therotational movement of the lifter. With the lifter raised in thismannner corner 56 of the lifter engages the round 22 at the end 43 ofthe magazine, holding the stack of cartridges against movement from theforce of compression spring 29.

When the bolt 16 is released by trigger 19 and travels to its forwardposition as seen in FIGURE 7, it rotates the lifter 49 to the loweredposition shown in that figure. This is accomplished by means ofprojecting ram 53 on the forward lower edge of the bolt which contactsthe rounded upper surface of arm 59 that is integral with the lifter 49.

When the lifter 49 is rotated downwardly in this manner the cartridge 22at the end 43 of the magazine is released, being no longer held in themagazine by the edge of the lifter. Therefore, the force of thecompression spring 29 acting on the plunger 28 causes the cartridge toassume the position shown in FIGURE 7. It can be seen that the rim 34 atthe bottom of the cartridge has been moved into the space betweenconvergent sections 61 and 62 of the sheet metal elements 51 and 52. Thebullet end 33 of the cartridge, however, is at this time held by a splitwire spring 64. This spring is mounted at the end 43 of the magazinewith its spaced end portions 65 and 66 projecting inwardly in front ofthe bullet 33 of the outer cartridge 22. Accordingly, this arrangement,by holding onto the upper end of the cartridge while the lower end isunrestrained, causes the cartridge 22 to pivot as it is moved out of themagazine.

This is of importance in overcoming the inertia of the stack ofcartridges when the magazine is full. It is necessary, of course, tomove all of the cartridges at once in shifting the end cartridge out ofthe magazine. Therefore, with a fully loaded magazine it would require avery strong spring to move the cartridges a sufficient lateral distancein anything less than an appreciable interval of time. In other Words,if the end cartridge were to be moved translationally a sufficientamount to align the rim end with the lifter, the entire mass of theassembled cartridges would have to be moved a distance approximatelyequaling the diameter of the rim 34. Moving all the rounds of a fullyloaded magazine such a distance would require time in overcoming theinertia of the stationary mass. Even with a heavy spring it would beditficult to achieve the necessary amount of movement in the briefinterval permitted when the gun is being fired rapidly. However, by theinclusion of the split spring 64 the end cartridge is caused to rotateas it leaves the magazine rather than shifting it rectilinearly. In thismanner the lower and lighter end of the cartridge is moved outwardly anadequate distance to escape the end 43 of the magazine, while theheavier bullet end is retained. For .22 caliber cartridges a movement ofonly .040 inch of the plunger will kick the lower end of the cartridgeoutwardly .250 inch to clear the magazine.

As the bolt 16 is moved back toward its cocked position by the gasesfrom the fired cartridge, or from manipulation of the lever 17, theprojection 58 of the bolt will retreat so as to allow the lifter tocommence counterclockwise rotation about shaft 50. Therefore, the lifter49 will progress from its lower position of FIGURE 7 to an intermediateposition such as seen in FIGURE 8. Here the surface 67 of the lifter isbrought into engagement with the bottom end 34 of the cartridge 22 whichpreviously had been pivoted outwardly into the path of the lifter. Thelifter then begins to raise the cartridge upwardly, causing the bulletend 33 to engage the outwardly beveled surface 63 at the upper edge ofend 43 of the magazine. This surface acts as a cam, forcing the nose ofthe cartridge outwardly away from the magazine as the cartridge startsits vertical movement. The torsion spring 53 that actuates the lifter 49readily overcomes the relatively small retaining force offered by thesplit wire 64. Consequently, while rim end 34 of the cartridge isinterposed between the relatively widely spaced sections 61 and 62 ofthe members 51 and 52, the nose of the cartridge is brought into apassageway defined by additional sheet metal guides 69 and 70 whichextend upwardly toward the receiver of the gun. The members 69 and 70also serve to attach the feed unit to the gun by means of the bolt 71.

As the cartridge continues its upward movement under the impetus of thelifter 49 it is brought into a position as illustrated in FIGURE 9. Hereit may be seen that the central portion of the cartridge is engaged onthe left by a second split spring member 72 (see also FIGURE 10). Thespring 72 is made of spring wire and includes ends 73 and 74 thatproject through slots 75 and 76 in the guide elements 69 and 70.Preferably these spring ends incline upwardly toward the rear of thegun, and are bent to present smooth arcuate surfaces that extendinwardly of the guide channels 69 and 70.

As the lifter 49 cams the bullet off of the beveled surface 68, thespring 72 assures that the cartridge will not receive a counterclockwiserotation as it approaches the receiver of the gun. In other words, thetop portion of the cartridge is prevented by spring ends 73 and 74 fromflipping over to a position where the bullet end 33 would be facingtoward the rear of the gun rather than the muzzle. Thus, the spring 72makes certain that the cartridge will be inclined forwardly as it islifted upwardly toward the gun.

The vertical movement of the cartridge to the position of FIGURE 9 alsobrings the rim 34 of the cartridge into engagement of the bottom edges77 and 78 of the guides 69 and 70. The members 69 and 70 are spacedappropriately so that all portions of the cartridge can enter betweenthem except the rim 34. Thus, edges 77 and 78 stop the rim and halt thevertical travel of the cartridge at this point. Consequently, the lifter49, which now has been rotated to where surface 67 engages the cartridgetoward the forward edge of the rim 34, causes the cars tridge to rotatein a clockwise direction. As this occurs, the spring 72 acts as afulcrum about which the midportion of the cartridge pivots. Hence, whilethe rim portion 34 is driven to the rear, the cartridge is caused torotate forwardly about the spring ends 73 and 74.

The convergent portions 61 and 62 of the lower guide members connect toa more closely spaced section defined by parallel sheets 79 and St). Theinner walls of these members are spaced apart substantially the samedistance as the walls of the guides 69 and 7d. The sections '79 and 89have rearwardly inclined edges 81 and 82 which are in an opposed spacedrelationship with edges 83 and 84- of the guides 62? and 7 3. The edges,therefore, define a guide slot for the rim 34 of the cartridge. Hence,as the cartridge is pivoted about the fulcrum of the spring ends 73 and74, the rim is trapped between edges 81 and 82 on one end and 83 and 84on the other so that the cartridge must follow a predetermined path.

Additional rotation of the lifter 49 brings the cartridge to the nextposition as seen in FTGURE 11. Here the rim is still retained betweenthe edges of the members 69 and 7'9 on one hand, and '79 and 84 on theother. However, at this point the intermediate portion of the cartridgehas passed the fulcrum of the spring ends 73 and 74. The force of thelifter causes the cartridge to move the spring ends outwardly throughthe slots '75 and '76 in members 69 and 7d as the round is movedupwardly. Thus, the spring 72 provides a yieldable fulcrum which acts asa pivot point for the cartridge during only a portion of the movement ofit. At the appropriate time the cartridge is forced through theconstriction of the fulcrum overcoming the spring '72 to move the ends73 and 74 outwardly.

deuce, the spring 72 performs more than one function in directing thecartridge in the proper path so as to enter the gun receiver. First itacts as an abutment to prevent the bullet from rotating to face the rearof the gun. Next it serves as a fulcrum about which the round pivots.Finally, the spring 72. yields to allow the cartridge to travel upwardlytoward the breech of the gun.

Upon complete retraction of the bolt 16 the lifter reaches its fullyrotated position, as previously described, where the stop 55 limits itspivotal movement. Vt'hen this occurs the end 86 of the lifter engagesthe lower end of the cartridge and prevents it from dropping downwardly.The nose of the cartridge cannot move in that direction because it isadjacent the wall portion 87 of the breech area. 0n the outer side ofthe lifter at the end there is included an upwardly and laterallydirected extension 88. This assists in retaining the cartridge andassures that it cannot fall outwardly through the side opening 18.

It can be seen, therefore, that when the lifter has been rotated to itsraised position the cartridge 22 is brought into a position of accuratealignment with the bolt 16 and the chamber 89. Consequently, when thetrigger releases the bolt, the cartridge is ready to be chambered andfired. Of course, as the bolt moves forwardly in this manner, theclockwise rotation of the lifter 49 is commenced by the ram 58 so thatthe end 86 of the lifter moves out of the way in time to permit the boltto drive the cartridge forwardly.

All of the above described movement takes place with great rapidity asthe gun is triggered and fired. The cartridges are successively movedinto the feed guides and driven upwardly by the lifter in a brief momentof time. The feeding device operates reliably regardless of whatquantity of cartridges there may be stored in the magazine. An entirebox of cartridges may be fired in this manner as quickly as the triggercan be pulled. Nevertheless, despite the fact that the feeding action isextremely fast and accurate, the components of the feed unit can bemanufactured quite economically. Sheet metal is used extensively and allof the parts can be fabricated and assembled without difficulty. Theunit is compact and of light weight which is a matter of considerableimh portance in a hand held gun. The entire unit is adapted to becovered by the gun stock so that it is inconspicuous when installed.

The magazine is loaded very easily by slipping the cartridgesindividually into the end 43 of the magazine as seen in FIGURES l6 and17. They are fed in from belov being guided by outwardly flaring flanges90 and 91 at the lower edges of the members 51 and 52. The flanges forma guide directing the cartridges into the end of the magazine where theyare received between the Walls 44 and 45. Each cartridge fed in, ofcourse, forces the remaining cartridges toward the opposite end of themagazine until the magazine is fully loaded. The lifter 49 should be inits raised position as the rounds are pushed into the magazine so thatthe edge as can retain the cartridges in the magazine.

The magazine 24 is quite easily unloaded by moving the assembly of thelitter and the guide members 51 and 52 away from the end 43 of themagazine. The sheet metal elements 51 and 52, which carry the mountingshaft in of the lifter 49, are pivotal relative to the fixed portion ofthe magazine by means of a transverse pin 93 carried by members 69 and70. The lower edges of members 51 and 52 also include hook ends 94 and95 which bear against a second transverse pin 96 when the magazine is inthe closed position.

The releasing latch is in the form of a U-shaped member 97 which hasapertures complementarily receiving the pin 96. This pin passes throughthe body of the magazine where it is received in longitudinallyelongated slot 93. A longitudinal opening 99 extends into the magazinebody and receives a compression spring lltlll. One end of this springcontacts the pin $6 while the opposite end bears against the pin 93.Consequently, the spring 1% biases the elements 51 and 52 to a positionwhere the hook ends 94 and 95 engage and are retained by the pin 96.

For release, the latch member 9? is moved toward the end 33 of themagazine. That is to say, the latch 97 is moved to the left asillustrated. This travel of the latch is permitted by the fact that itincludes slots 161 and m2 at the location of the pin 93. When the latchS97 is shifted to the left it moves the pin out of engagement with hooks94 and 95. As a result, the members 51 and 52 are free to pivotdownwardly about the pin 93 to assume the position shown in FIGURE 18. Therefore, the entire front end of the magazine is left open and thecompression spring 29, through the plunger 28, then can force all of thecartridges out of the magazine. Hence, it is a very simple matter toempty the magazine whenever it is desired.

From the foregoing it can be seen that I have provided a very simple gunfeeding device, but, nevertheless, it is dependable in operation andrapidly moves a large quantity of cartridges successively into thereceiver of the gun. All aspects of the operation of the device arequite simple and all of the feeding operation takes place automatically.
